ABSTRACT:
An horizon projection device for an aircraft simulator.
The device comprises an aerial image 4 of a part of the Earth's surface, an optical image projector comprising a variable magnification system 13, an optical scanning device 18 and a wide angle projection lens 17. The optical system 13 forms in the focal plane of the wide angle lens 17 an intermediate image whose dimensions depend on the magnification. Controls responsive to the altitude, to the attitude and to the heading simulated by the pilot act on the magnification of the optical system 13, particularly to correct an apparent altitude variation due to the shift between the eyes of the pilot and the wide angle lens, during simulation of the aircraft going over on to its back.
